Body fat is associated with increased and lean mass with decreased knee cartilage loss in older adults: a prospective cohort study

To determine the associations between body composition at baseline and knee cartilage loss over 2.9 years in older adults. A total of 395 randomly selected subjects (mean 62 years, range 51–81, 50% female) were studied at baseline and 2.9 years later. T1-weighted fat-suppressed magnetic resonance imaging of the right knee was performed to determine knee cartilage volume and tibial bone area at baseline and follow-up. Height, weight and...
